Shorted power button? - Samsung Galaxy A50 Questions & Answers

My a50 keeps flickering but not in a way that would make you think that the LCD has a problem.
Last night it poured really hard. My clothes were all wet and my phone was in my pocket too. Worked fine until just an hour ago. It's as if the lock button was being pressed at 20 times a second. Whenever it stops and I get to unlock it, it locks itself after a couple seconds and it just flickers over and over again. rinse and repeat. I took off the case and of course, there's moist mostly at the bottom and some to the sides. (not sure if the moisture was from last night though.)
The only way i could restart it is by holding Vol- and Power buttons. Screen is pretty much fine when displaying the Samsung logo, which makes me think it's not an LCD problem.

I just plugged the phone in to charge it and the problem just went away on its own. I'm just going to assume that charging it "un-shorted" it.

Spilled a small amount of water onto phone, now it boot loops

I accidentally spilled about a teaspoon or two of water onto the screen of the GS3. I guess water seeped between the screen causing the phone to power off. I took the battery out and let it dry for two days, but it's still not powering on. What happens when I insert the battery and hit the power button is that I get a vibration, the splash screen of the rom comes up and then the phone powers off.
Plugging the phone into a wall outlet or computer without the battery I get a vibration, the red LED light comes on for a second and then powers off. The computer won't recognize the phone. Is this phone toast?

Should have disassembled it and put the parts in a bowl/bag of rice.

Stop trying to power it on (it only makes things worse) and do what Aerowinder said, take it apart and let it sit in rice. After two days put it back together and see if there's any improvement. If the phone does the same thing after sitting in rice, you may want to try a different battery if you have one or can get a hold of one.

[Q] Desire wont start up. The screen just keeps flashing.

So i went out on a night out and my battery went flat whilst i was out. I come to start it after charging it up and it just keeps popping up with the start up screen for a split second and then going off. It keeps doing this until i unplug the charger or take the battery out. I managed to get into the reboot screen and tried starting it from there to no avail. The battery is only a couple of months old so that should be good.
I took it to a phone repair shop and they said the board was gone and that there was nothing that could be done with it. Is this the case?
I don't generally turn it off just keep charging when it gets below 20% battery life. I did however install solitaire since i last powered it down if this might have any influence on the situation.
Check if you can get into the bootloader. Hold volume down and power.

I have tried this but although it comes up with the bootloader screen it flashes off gain as with the boot up screen. It does not give you time to do anything in the bootloader.

Are you sure the battery isnt completely dead? Did you drop the phone or do anything that may have caused this, or did it just suddenly occur?

No i have charged and recharged it until the green light comes on. The chap at the shop tried another battery also and this had no effect on it.
I dont recall dropping it. It is in a substantial wallet holder so i would think that would take the brunt of the blow even if i had. But it worked fine all night until it powered down then it just started to play up.
Right while messing a bit further it seems to me that the on off button is constantly activating. If i just hold the return button it comes up with the reboot screen and allows me to choose the various options. If i hold the volume button the fastboot screen appears but disappears just as quickly. All of this happens with out me touching the on off button so it looks like it is constantly trying to start up. The button does not have any visible signs of damage. Is this a normal failure point for these phones?
If it charges completely while it's off, then the board should be fine. You can check the percentage in your recovery mode if you can get there.
If the board is fine, it either means that the button is stuck or you have some gunk short circuit in the button.
If it's gunk, you might get away with some rubbing alcohol, If it's in a spray can, even better. If it stuck, it should be opened and see what's keeping it pressed.
I hope this helps.

My galaxy will not turn on it just vibrates! Bricked?

Two weeks ago my galaxy just stopped working. it was at a decent battery; just stopped. I tried charging it but the phone would vibrate. phone would come on, then shut off. I tried it multiple times and same result; a few times the phone would make it to the samsung startup animation, sometimes it would just flash the samsung logo, once it compleley got to my screen start before shutting off.
I brought my phone to get fixed. It took a whole week and the guy said my phone was just not fixable. It would work for a few hours then shut off again, according to him. I suspect he didnt work much on it though as hed rather fix phones with easy problems as mine was a tough one.
I've had to replace my phone with an iphone now, but right now, out of curiosity, I completely took my phone apart, and started using tweezers to play the power on button. The camera part just broke off (not the actual camera) but now my phone is actually charging! The red light is on, and click the main button, it shows the battery being charged. This has not happened ever since the phone broke.
Am I bricked? Is there hope for this phone??? Please tell me there is lol.
EDIT: My phone seems to have restarted! Turned it on and it's asking for my simcard what is GOING ON LOL

idont know what you did there, but it worked plus you gotta be more specific to how the phone broke and could not boot-up to screen

It just randomly shut off. It was if someone would constantly be turning the phone off as soon as I turned it on. But then I couldn't even charge the phone. No red light, no screen, nothing, just vibration. I would try to turn it on sometimes it would get to the boot up, sometimes not, sometimes nothing, just a vibrate.
I literally took tweezers and lifted the green board out from around the power on button (it's an actual tiny white button on the inside). and then it randomly started working again

Could be a power button failure. Happens somewhat often.
Could be battery related too, a cheap replacement battery could strike that off.

agree with what he said, it could be a problem with the power button or battery is not working
off topic did you really get 176Mb/s download or is it fake
if its real then was it WIFI or DATA , i have never topped 50Mb/s both wifi and data) but DATA seems to be 10x faster than my wifi

G4 Screen very slow to wake / Water Damage

Hi,
For background...
I have the H815 and had no issues. Until I had the misfortune of it falling out my back pocket into the toilet after doing my business
In a flash I had it out, powered off, battery out, etc. Then being a little too hopeful that water didn't get in too far I tested it, it still worked, but I could see water behind the screen, so I removed the battery and let it dry overnight. Next morning it wouldn't turn on.
The good news is after pulling it apart, cleaning it with Isopropyl alcohol it's up and going.
My issue is...
It now generally takes 5-10 seconds for the screen to light up, regardless of if it's via the power button or knock knock (which now misses 70% of the time, you can tell when it works cause the LED flashes blue, then 8 seconds later the screen wakes up).
Once the screen is on, it often refuses to register any touches, so I can't put in my swipe pattern.
If I'm lucky enough to get through the unlock screen everything works 100%. No issues with the touch screen. No lag whatsoever. Knock off works seamlessly. Everything is fine.
I've tried a factory reset, and changed between having a pattern unlock, to just swipe, to no lock screen.. etc. Nothing seems to have an effect. With the no lock screen option I've had it wake up using knock knock, and then not register any touches.
Should I be pulling it apart again and trying an extra soak of the motherboard in the Isopropyl while the screen sits in rice?
Seems strange that everything works so well, just the wake-up process being the problem.

Nexus 7 Gen 2 won't turn on

Okay, here's the story. My Nexus 7 Gen 2 went into the water for half an instant. However, when I tried to turn it off immediately, it wouldn't turn off. I put it in a container of rice for a couple of days and eventually, it turned off - the battery died, I'm sure. Anyway, now, when I plug in the charger, I get the battery charging symbol, however, it will still not turn on. I've tried some of the button combos mentioned (hold power for 30 seconds, hold power and volume up for 3-5 seconds, hold power and volume down for 15 seconds, even hold power for 2 minutes), yet nothing seems to work. But as soon as I unplug it and plug it back in the charge symbol appears. Any suggestions?
Thanks!
Chris
Okay, read some more on here and got it into boot load mode. Pressing the up arrow puts the start arrow at the top of the screen pointing to the power button, the down arrow "restart bootloader", however, pressing the power button does nothing.

hw version - rev_e
bootloader version - flo-04.06

If you put the tab in the rice container without removing the back, you don't know if all the moisture that seeped in has been removed. You need to disassemble the thing, dry each and every component inside with a blow dryer ( both sides of the electronic boards) to make sure of that. Thereafter, you can try again. Because even if you succeed in flashing the OS anew, you'll never know when the residual moisture will interfere or affect the components again.

I didn't use a blowdryer, but it sat out on a table with the back off for about 24 hours and I do live in southern Colorado in the high desert, so humidity isn't a huge factor. I may give that a try today, though. Thanks.

I'm afraid some corrosion has set in already and it may not be reliable anymore.
Next time, you should immediately disassemble it and disconnect the battery, then use a hairdrier to remove the moisture ASAP.

So, given that it will open into the reboot screen and the volumen buttons seem to work but the power button itself doesn't work, could it be possible to replace the power and volume buttons and get it to restart? Just wondering if I can manage to salvage this thing.

Yes, try to replace or test with multimeter the control buttons assembly first but if it does not help then remove the motherboard and its shields, and check it for any visible signs of corrosion. Scratching off a conductive corrosion layer may fix it.
